COMBINED LOCK AND LATCH.

Specification' of Letters Patent.

Patented July 6, 1915.

Application led April 5, 19'15. Serial No. 19,261. l

T0 @ZZ whom it may conc-ern y Be it known that I, FRED CoLEMAN, acitizen of the United States, residing at Danville, in the county ofVermilion and State of illinois, have invented certain new and usefulImprovements in Combined Locks and Latches, of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to certain improvements in combined locks andlatches; and it is an object of the invention toprovide a novel andimproved device comprising a minim'um of parts and affording a maximumof eliiciency. n

Furthermore, it is an object of my invention to provide a device of thisgeneral character especially designed and adapted for use in connectionwith a swinging door and having novel and improved means whereby thedevice will operate to maintain the door in proper contact with the jam.

It is also an object of my invention to provide a device of this generalcharacter particularly applicable to screen doors and the like andcomprising a novel and improved structure whereby the same is free ofany projections or the like which would vpossibly injure an objectbroughtk into contact therewith. l

The invention consists in the details of construction and in thecombination and arrangement of the'severalv parts of my improvedcombined locl and latch whereby certain important advantages areattained and the device is rendered simpler, less expensive andotherwise more convenient and advantageous for use, all as will behereinafter more fully set forth.

The novel features of the invention will be carefully defined in theappended claim. In order that my invention may be the better understood,I will now proceed todescribe the same with reference to theaccompanying drawings, wherein- `Figure 1 is an elevational viewillustrating a combined lock and latch constructed in accordance with anembodiment -of my invention and in applied position, the coactingj ambbeing shown in elevation and the coacting door in section; Fig. 2 is aview in top plan of my invention as herein embodied, the coacting jamband door being shown in section; Fig. 3 is an inside elevational view ofmy improved device, with the coacting hasp disclosed in an inoperativeposition; Fig. f1 is a front elevational view of my improved device; andFig. 5 is a fragmentary view in perspective illustrating the lock memberherein included.

As disclosed in the accompanying drawings, A denotes a fragment of adoor frame jamb adapted to be engaged by the stile B of a door andprojecting laterally from the stile B is the hasp member H included inmy invention as herein embodied, andsaid hasp member H is preferablyproduced from a single length of wire of requisite gage having oneextremity firmly secured to the stile B by having said extremity, asindicated at 1, provided with a gimlet pointed thread. At apredetermined point intermediate its length, the wire is bent to affordthe lateral bar 2 and the reversely directed bar 8, said bar 3 beingsubstantially parallel to the bar l on which the threads 1, hereinbeforereferred to, are produced. The bar 3 extends rearwardly a predetermineddistance and is then disposed downwardly on a predetermined incline, asindicated at 5, and terminates in the eye 6 adapted to bear against thestile B and through which iis directed an anchoring member 7, hereindisclosed as a conventional screw, whereby said hasp member is furthermaintained in applied position upon the stile and maintained againstdisplacement.

Anchored to the jamb A through the medium, as herein disclosed, of theheaded screws 8 is a casing C comprising a plate 9 maintained inpredetermined spaced relation relative to the jamb through the medium ofthe rear flange 10 and the side flanges 11, said side flanges 11 beingprovided with the laterally disposed perforate feet or extentions 14through which the screws 8, hereinbefore referred to, are disposed.

Adjacent its upper end, the plate 9 is provided with the cam slot 15 ofpredetermined pitch and into which is adapted to be projected the haspmember H, hereinbefore referred to, with the portion 5 of the haspmember exterior of the casing C whereby itwill be perceived that thelateral bar 4L operatively coacts with the slot 15. The inner and majorportion of the lower wall of the slot is segmental and affording ashoulder 16, for a purpose to be hereinafter more particularly referredto. At the axial center of the segmental portion of the lower edge ofthe slot 15 a disk 17 is operatively engaged with the plate 9 andadapted for rotary movement, said disk being provided in its peripherywith a radial open end slot 18, the base whereof being substantiallyflush with the segmental edge portion of the slot 15 and projectinginwardly and laterally from thelower portion of the inner side wall ofthe radial slot 18 is the lip or projection 19 serving as a buffer withwhich the bar l of the hasp member H is adapted to abut and alsoaffording an anchoring means for an extremity of the retractable member20, herein disclosed as a conventional coil spring, possessing therequisite tension, the opposite extremity of said retractable memberbeing secured to the tongue 21 struck from the lower end iange 11. Theinward movement of the disk 17 is limited by the contact between` thelip or projection 19 with the inner extremity of the slot 15, while theoutward movement of said disk is limited by the contact 'of said lip orprojection 19 with the shoulder 16, hereinbefore referred to, and itwill be readily perceived that the retractable member 20, hereinbeforereferred to, will serve to automatically maintain the disk at the limitof its movement in either direction after the hasp member H has causedthe lip or projection 19 to pass a vertical center.

When the disk 17 is at the limit of its outward movement, the open endof the slot 18 thereof intersects the outer or open end of the slot 15so that the hasp member H may enter within the slot 18, and it is to benoticed that the bar 1 is of such a length as to assure the disk 17being forced inwardly beyond its vertical center whereupon theretractable member 20 will automatically serve to assure the requisitecontact between the jam A and stile B even though said stile be warpedas often occurs in practice especially when a screen door is employed.The disk 17 has produced therethrough an opening 21 which', when saiddiskis at the limit of its inward movement, is in alinement with anopening 22 producedin the plate 9 and through which is adapted to beinserted the locking pin 23 whereby it will be perceived that the disk17 will be effectively maintained against outward movement and the dooreffectually locked. As herein embodied, the pin 28 depends from anextremity of an arm 24: projecting at right anglesy from a stem 25rotatably mounted within a cleat or sleeve 26 carried by the rear iiange10 of the casing C and of such a length as to readily permit the lockingpin 23 to be applied to or removed from operative engagement with thedisk 17 and also permitting said pin to be swung in a position away fromthe casing when the same is .not intended for use.

From the foregoing description, it is thought to be obvious that acombined lock and latch constructed in accordance with my invention isof an extremely simple and comparatively inexpensive nature and isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled, and it will'also be obviousthat my invention is susceptible of some change and modification withoutma'- terial departure from the principles and il spirit thereof and forthis reason I do not wish to be understood as limiting myself tothe'precise arrangement and formation of the several parts herein shownin carrying out my invention in practice. i

I claim:

A device of the character described including a plate provided' withsecuring means and with an open cam slot, a hasp member adapted to bereceived within said -1 slot, a disk rotatably supported by the plateand provided with a recess in its periphery also adapted to receive thehasp member, coacting means carried by the disk and the plate forlimiting the movement of the disk f'- in opposite directions, automaticmeans for imparting movement to the. disk when the recess of the disk iscarried by a center, said plate and disk being provided with openingsadapted to register when the disk is at the limit of its movement in onedirection, an arm rotatably supported by the plate and disposedlaterally of the disk, a stem carried by the arm adapted to overlie thedisk, and a pin projectingl inwardly from i y the stem and adapted to beinserted through the openings of the disk and the plate when inregister, `the rotatable arm being also capable of endwise movement.

In testimony whereof I hereunto aiiix my signature in the presence oftwo witnesses.
